Leaf issue that doesn't fit

[Owlgrower]

Hi, this is my first post here and like many others, I'm starting a thread cuz I'd like to know WTF is going on. Basic plant info:
- photoperiod, grown from seed
- age: 2.5- 3 weeks (not sure when to start counting)
- grown indoors in soil. Just random potting soil I picked up in the nearest garden center
- grown in plastic pots with a lot of holes drilled in the sides to counteract the shitiness of plastic pots (might not help at all)
- no added nutrients, just what's in the soil + calmag to offset a very soft water I have
Now for the actual issue. Plant is very short with very tight spaces between nodes. And it's supposed to be 60% sativa. Pretty much after week 1, the oldest leaves started yellowing with brown spots randomly. Usually brown at the tip but not other edges. First true leaves are already gone, now it's progressing thru second set of leaves. So it starts from the oldest. The way it looks doesn't quite fit common issues I've searched.
- first I thought over watering but it's now been without water for 3 days and it's still progressing

P. S: pay no need to the wonky LST, there was some misshapedness to counteract.

when you say soft water you dont mean water that is run through a water softener do you??

feed it some veg nutes at about 350 ppms
looks like it might be low on P from the brown spots im seeing, wouldnt worry about it much if you feed it something.

No, no water softener. Just the water source here happens to be really low on minerals

i wouldent worry about those leaves, i have them on one of my amnesia haze plants too, the rest of the plant is okand new growth isnt affected

You need to feed next time you water.

oops my bad, didnt finish reading it first. yes feed them

heres my hemp cbd haze i believe

Thanks for the replies. I will try some light feeding and see what happens. I wasn't expecting having to add nutes so early to soil.

I'm willing to bet that is not enough calmag...I had the EXACT same thing. Mine needed almost double the calmag. Mine were cal pigs and I have kept calcium double right through to week 5 flower and haven't had an issue since.

Calcium doesn't toxify quite as much as other nutes and you can easily add extra without harm.

Just ny $0.02 worth

Well, I ended up giving it a full spectrum of nutes appropriate for veg at a lowered dose. That includes calcium and magnesium. My hope is I won't see any toxicity/burn going forward. But, in the end, we learn from our mistakes XD
